The Role Of Artificial Intelligence In Enhancing Blockchain Security

Topic Information

Dear Colleagues,

Blockchain technology, which allows untrusted individuals to connect with others in a verifiable manner, has attracted much attention from both academia and industry. It is now used commercially for various applications such as tracking ownership, digital assets and voting rights. Blockchain is transforming our daily lives in every aspect, including banks and other financial institutions, hospitals, companies, and governments, among others. To make a blockchain application smart, Artificial Intelligence (AI) is being widely studied, which can build smart machines capable of performing tasks that typically require human intelligence, such as the ability to reason or to learn from past experience. For instance, AI algorithms can help blockchain applications handle data more efficiently without human intervention. The intelligence provided by AI can also benefit the design of smart contract in blockchains. Now it is possible to create deep learning neural networks, which can perform quickly and accurately for real-world blockchain applications.

The use of blockchain can provide various merits, such as transparency, data integrity, and enhanced security. By combining AI with blockchain, there is potential to make a real-world system more secure, intelligent, and efficient. For instance, blockchain can be used to ensure the integrity of shared data or models that would be used by AI, including deep learning and many machine learning techniques. The blockchain-empowered AI system is believed to be more robust against adversarial attacks. However, such a combination is not mature at the current stage, and many challenges remain unsolved, which are highlighted as follows: (1) Blockchain suffers many performance limitations, i.e., when the nodes or transactions become large, its efficiency is significantly degraded. (2) Both blockchain- and AI-based systems may leak private information, especially when the system aggregates data from various nodes. (3) Blockchain and AI systems are the main targets for cyber attackers, and various attacks have been posed on these systems, such as the 51% attack, double spending attacks, etc. Hence, how to combine blockchain with AI in a secure and intelligent way needs more research efforts.

This Topic focuses on using blockchain and AI to secure applications, software, data and systems. We invite original research, practice and surveys that investigate securing applications with blockchain and artificial intelligence. The topics of interest include, but are not limited to:

  • Machine learning for privacy preservation and system security
